This invention consistsk First, in :in improved construction ot' theways which guide the movement ot' the iuking-rollers, suid we vs bearingsuch relation to the nlcdistributingcyl- ,inders as to insure :ui enstmovement to said rollers,

' und, :it the sume time, unse them free from thedistributiiigt-cylinders on coming in Contact with, or leuving thesinne, mid thus :ivoid the tcuringot' rollers so iiequent in presseswhere the t'oriner are drnwn over the dist-i'iln1tingcyliluiers. l

Second, in the ,construction und use otl cuius, which the gripper orrisk'et-ii'nger,

govern the movements ot' the drew-hairs, in cmmection with thedriving-ermilcs.

Third, in t compound lever i'or giving motion to the hiking-rollers, one'ot' the .single levers ol` which `:ilwm/s hns e positive motion :it thetime oi'inlting the typesmvhile the other parts muy be dismmnectcd, il'desired, leziving the inking-rollers upon the distributing-cylinder orcylinders for u longer distrilnxtimi. When the simple levers forming thecompound lever ure connected, und `not together, szlid inking-rollershaven. positive motion in both directionsover the types, never beingr:illowcd to rundown by their own weight. Y y f Fourth, in ai device fordisconnecting the single lc- -vers ot' which such compound lever isnnule up, und rendering one portion ,of the sume, together with theinking-roliers, inoperative, while the reimiining lever continues in thepositive motion above described.

Fifth', in n'cntchfor preventing thc sziid diseonnecting-device frombeing released :it :my other time tlm-u when the single levers,composing the compound lever, v:ire in proper position for conneciion.

,lightlu insprings, l|nlia-rubbcr packing, or other elaistie nutterinl,to tithe oii the positive pressure ot'the ink-ibuntuin set-screws, so:is to prevent the bilnling.; ot" the gziuge or cut-ott' upon `thesuriiu-e ot' the roller which fee-ds the inlii'ronl the trough or funk.

Ninth, in placingon the lover-proiection oi' the plntrm-rocker n lug,which, in connection vwith :tiizrnge or stop ou the tranne-work, holds'the pinten in position during the impression.

Tenth, in giving the. typo-bod u. bnckwnrd inclinetion, when used with urocking, rolling, vibrating, or oscillatingr platen, for the purposeo't' iii-stelling the form to the i'nce of the bed by its own grovity,preventing loose type trom wol/hing ont, :md the. form bngging. l lu thedra-wingslhe way al ai* lr a,'wjiich governs the direction oi' the.rollers Il, 2, 3, hns :i straightpau-t, in line with the time ofthetypes, and :t series ot' curves :it `thutlmrt nearest theink-distiilmting cylinder or cylinders.V

This series ot' curves maybe varied iordiiierent numbersot'hiking-rollers.` ln iig. l, threehiking-rollers nrc. represented, l p:Ls-resting upon the distrilmtingfeylinders 4 lhe direction of movementot' the wheels or guides acts in unison-with the strrd or wheel (J,

back again to their' position 'l' 8 determines the direction of thehiking-rollers, as they leave and approach the distrilrating-cylinders.

Roller 1 simply cornes in contact with cylinder- 5, and leaves itdirectly, passing toward cylinder 4. At the same time the rollers 2 and3 are lifted ottl from cylinder 4, without being drawn over' itssurface..

This is donc by the movement oi' the wheels or guides S into the curvedi.

As roller I nears cylinder' 4, it also is raised clear of said cylinder,bythe passage of wheels or guides 7 into curve af. The wheels or guides7 and 8 then both pass through curve ai' into the straiglrt part ai.

It will be seen that the passage of tile wheels or guides 8, through theseries of crrrves a e2 a", into the straight way ci, will give an easy,undulating motion to the rollers, and, at the same time, willv pre ventthe' composition ofthe rollers 1, 2, 3, from being torn, as it is liableto be when said rollers are drawn over the surfaces ot the cylinders inthe usual manner.

lt, will also be seen that this arrangement so re-` moves-thehiking-rollers and distributing-cylinders from the plane ot' the face ofthe types as to allow the printing of sheets larger than the face of theplaten, or with margins extending beyond the face ot' the platen, andthus prevents the contact of said sheets with the ink upon said rollersand cylinders.

ln lig. 4, the traverse-cam U, iuconnection wit-lr stud or wheel i,governs the 'movementot' draw-bar l), while thccrank-pin e is passingthrough the slotd.

l)uring-a part otthe sweep of the crank-pin e, it 'that part of thetraverse through which the stud'or wlrecl is passing` being concentricwith the crank-pin.

The remainder oi' the traverse being eccentric to the crank-pin, allowsthe said movement oi' the latter in the slot (l, at the same timeholding the draw-bar quiet, so as to impart a time ot' perfect rest tothe :plate The traverse may either be a cap, as represented, to beattached to the crank-pin outside of thecdraw-har, or it may form partot' the crank-wheel inside of the drznv--barn l 'lhe combination ot'levers for giving motion to the inking-rollcr's is a rranged as follows:

ll, ligs. 'l and 2, is a shaft, to which roller-arms I,--

iig. l, are attached, through whichtby any means ot' connection, motionis given to the inking-rollcrs of a press.

'.lo shaft H, l attach a lever', K, which may be entirely separate fromthe roller-arms or levers above mentioned, or may form part ot' oneofthem.

l also pivotlanothcr lever, L, at H2, tigs. 2 and 3, said lever having apositive vibra-ting motion, at the iinr e,tbr moving the inking-roller'sover the types, and

on the*distributing-cylindcrs, such positive. motion being impart-ed bya stud or whccl,(), working in positive traverse-earn U' ot' the mainspur-wheel l", to which traverse-earn, nrotion is communicated by the,driving-shaft F.

Y I connect the levers L and K by means of a hookconncction, M, pivotedtolever K, at E", and hooked upon a strrd or pin, E, attached to leverL.

lt will be seen, that when levers L and K are. in the posit-ion shown intig. isi, by raising the hook M iom the stud Ef, the lever L will be,allowed its positive movement;without motion ofthe lever K, and,whenever' the hook )l is hooked upon the strul ll, both levers L and Kwill have a positive rrrotion, acting as a connected compound lever.

As lever L acts through the shaft H, to which the roller-arms orroller-levers arc attached, it will be seen lthat the inking-rollcrs,when moved 'in either direction over the types, will have a. positive.motion, or that said rollers may be retained any length of time upon theinking-cylindcrs, for distribution, by disconnecting the levers L and K,when in the position'represented in lig. 3.

4said wedge For disconnecting said levers, I use the lever N, withshort` arms y, said lever being pivoted atf.

It will be seen, in fig. 3, that by working the lever N, the short arm gwill raise the hook M, and discouneet the levers L K. \Vhcn the hook Mis lifted end of short arm g ot' lever N moves toa position in front ofa-projecting portion, 1', of lever K, which portion acts as a stop toprevent any movement of lever' K dlp-ing a complete vibration, or anumber of vibrations, ot' lever L.

A drip-hook or latch, I, drops into a connection with a rnortisc in theend ot' the short 'arm g, and prevents thc lever N from being worked,except when the levers" L and K are in juxtaposition.

The latch l is relieved from the nrortise inthe end of short arm g by aprojection, I?, drivingr against a profrorn the stud E", the

ejection, t", of said latch.

1twill be seen, that as vsoon as lever L 'moves away from lever K, thclatch I will fall into position, and prevent the working of lever' N atthe wrong time, and prevent dropping ot' hook-connection M.

Upon thc pins, trnnnions, orjournals I, igs. 10, 11, 12, and 13, whichsustain the force or draught of the impression ot' a printing-press, Iplace curved wedges or sleeves i` or i, the concave face of' said wedgesor sleeves being concentric with and in contact with said pins,trnnnions, orjournals I, said wedges or sleeves being placed betweensaid pins,- trnnnions, or and their journal-boxes or bearings.

The convex or outside face ot' said wedge or sleeve is concentric withand in contact with a part or wlrol'e of the concave or inner' face ot'said box or bearings Irl, the latter rrr-.1de either movable orstationary, in connection with the frame-work, type-bed,o'r platen, saidtrarne-work, bed, or platen being constructed in any manner', whetherthe tace of said type-bed, or thel plate for receiving the sheet, isplane, cylindrical, segment-al, or ot anyot-her construction; orwhether' the outside box or bearing M (either movable or stationary) isrrscd either in connection with impressionbars, connection-rods,draw-bars, or their equivalents, or forms apart of the same.

. By turning the sleeve or wedge i i? to ditere'nt positions about thetrnnniorr, pin, or journal I, the impression may be changed, to anydegree, from zero to the strongest power ot the press, according as theposition of said trunnion, pin, or journal is thus changed wit-h respectto t-lre box or bearing M3.

As the surface ot' pin or journal I and concave face ot' wedge or sleevet" i, are concentric with each other', and the outside face ot' -saidwedge or sleeve and the 'face of the box or bearing are concentric witheach other, said outside and inside faces ot said wedge or sleeve. beingonly slightly eccentric wit-lr each other, it Iwill he seen, byreferring to tigs. 11 and '12, that the tendency ot thc wedge or sleeveto turn under draught or l'rressurc, when set in any position, is veryslight. vIn tig. 1l the. wedge v" is 'represented as a completecrescent, and in tig. 12,"it is increased toa. sleeve. It will be seen,that when under pressure or draught, onehaltl ot' said wedge orsleevetends to move in one direction, and the other half in an oppositedirection, as shown b v the direction ofthe arrows in tig-1l and iig.12. As but little diti'crence in the positions of or sleeve is necessaryfor any change required in the impression, the variation between thetendencies to turn in either' direction will be slight, and more thanovercome by the friction of the surfaces under pressure or draught. Nodevice, therefore, is necessary for holding the wedge o-r sleeve inposit-ion while under pressure or., draught. Sonie devicc,'howcver, isvnecessary for moving and setting said wedge or sleeve` to the degree ofimpression required, and, whcretwo or nrore of said wedges or sleevesactin rrrrisorr, sornc device is required for connecting them ftogcthcr.

journals v In the latter ease, Iuse the connect-ii.|g-b ar T, tig. 14,or an equivalent. i

As thef'riction ot' thel bearing-surfaces in 11 and 12, more thanovercomes the tendency` ot' the crescent Ai2 to turn under pressure ordraught, the position of the crescent cannot be changed when desired,with ease, when any great amount of pressure or draught remainscontinuous. In -such a case, I cut one limb et' the crescentaway, moreor less, thus destroying the equipoise of the .two limbs, as shown infig. 10, or cut one limb of' the crescent entirely away, forming thecurved wedge 'i2 'of iig. 13. In that part of' the press A2, fig. 7,which contains or supports the pin, trunnion, or' journal, with `whichsaid wedge or sleeve comes in contact, I place a conical-headed screw,the head of which forms a V- shaped catch, L2, for the catch-hook XV, inwhatever position the screw L2 may be turned.

In fig. 1, T represents a projection upon the sleeve or wedge fi, i2, ora bar, connecting Vtwo or more wedges vor sleeves,`when more. than` oneare required. Upon the projection or barfl, is a handle, of' thefbllowing construction 'llhrough the socket U passes a rod, with a .ballor handle, Y. Upon said rod is a socket-spring, a, tig. 8, and attachedtothe cud of the rod, opposite handle V, is the catch -hook NV. Bypressing upon the ball or handle V, the hook W will be released from thecatch L2, and the wedge or sleeve vi iP', iigs. 1 and 14, may be turned,at will, to any position within the scope of its movement. To set theimpression to any particular degree desired, it will only be necessaryto move the cone L2, by turning the screw to which it is attached, out,or further into the supporting-part A2, and bring-4 ing the hook W' landcone l? into connection. This will vary the position ot' bar orproject-ion l`, and thus vary the position of' wedge or sleeve 1' i2,figs. lV and'14. y y

The manner of working the ink-fountain and vibrat ing feed-roller isrepresented in fig. (i.

.The crooked lever V* works the pawl V, by contact with a cam, Y, on thccrank-wheel F.

rI he ink is fed from the fbuntain-roller u2 on to the vibrating rollerY, while rollers n2 and V are in contact, such feeding being effectedbythe working ot' the lpawl Y and ratchet nl; and thesame movement of'said pawl being continued, forces the vibrating feedroller V6 againstthe distribnting-cylinder 4, said pawl pressing,r against the vibratingyoke V2. 'lhisrequires but one movement f'or feeding the ink from thefountain on to the vibrating feed-roller, and also for working thevibrating feed-roller to and from the distrib# uting-cylimler.

I, coat or line the tank or shell n, fig. 9, which coutainsthe ink, ot'an ink-fountain, with porcelain or other substance non-corrosive to ink,to prevent the metallic substance of said tank or shell f'rom eorrodingor discoloring the ink. v

The construction of' the bed l is shown in tig. 15, showing an end viewand a longitudinal plane section.

The f'ace of the bed is represented by B, the Vlongi-I tudinal bracesare Vrepresented by 7' l", und `the transverse braces by l. y

The core-prints or vent-holes, made in casting,` are represented by If,and F5.

The several braces ot' the bed converge to a ecmmony bearing-line, E,which corresponds with the driving-shaft Ill of fig. 2.

The bed, constructcdyl-s above described, may be made, together with thesupporting frame-work, in one piece. In such ease, said frame-work willform the end braces l, the be`d still remaining a hollow-chainberedshell, the core-prints making the openings er vent-holes I1" F5 throughthe` sides of the supporting frame-work, in those parts which fbrm theend braces. In applying thc spring material to the ink-fbuntain f 3,fig. 17,on the ink-feed roller S", 17, I use the following method, asone ot' the most convenient in manufacturing and dura-bib for use:

`l place a piece or pieces ot' rubber packing or other elastic material,h, upon the knife or cut-off f, said material being removed far enoughfrom the edge of' 'said knife as to avoid contact with the ink; I tbenplace upon this elastic material a thin bearing-plate or slips, f7, toreceive the direct pressure off the setscrews e Tile pressure of saidset-screws is conveyed indirectly to the ent-ofi' f3, but prevented frombeing a positive lirresistible pressure by the intermediate elas-v cutott' on any part of the length of the roller S", without binding 0rset-ting said roller.` Y

The gauge thus constructed is 'made movable, so lthat it may be cleanedseparately from the roller The holesn u, tig. 16, in thefi'isket-finger, are made large enough for small feed-guides to beplaced under them 'on the tympan-sheet. These holes have two prominentadvantages over notches cutinto the side of the finger: til-st, thefinger is lunch stronger, having material left on all sides of the hole;and second,

sheet, holding it in place more firmly, also preventing tearing orwearing Vfrail sheets, by contact with the corners made by notching thefinger.

S, tigs. 1 and .5, is the lug, placed on the lever-proieetion of' theplaten-support or rocker It, which draws upon the upper face of' theflange Y, while projection S2 draws upon the under facc. ot' saidflange, for the purpose ot' firmly holdin,"r the platen in positionduring the time for taking 'the'ilnpressiolt The bed I3,- tigs. l. land2, is made tovincline ba-ckward at any angle between fbrty-tive degreesand the, vert-ical, in order that the type may rest ,npon' the face oi'saidA bed, by its own gravity, preventing the loose type from workl terfrom bagging.

connection with a cylinder, b v (l. l. Gordon, and also in connectionwith a reciprocating platen inclined par-4 allel to the bed, by P. "\V.liatcher` v I'Ieretofbre the general construction ot' presses hasprecluded the use of abed inclined backward at the. same time with avibrating, oscillating, or rocking platen, on account oi' thenecessarily extended sweep of' the platen.

.By constructing a platen ot" the general nature of the one here shown,the sweep is unitevi-allyshortened, thus allowing the use of such a bed.

Having thus described my invent-ion,
